'''Firefly''', formerly named PC GAMESS, is an [[ab initio quantum chemistry methods|ab initio]] [[computational chemistry]] program for [[Intel]]-compatible [[x86]], [[x86-64]] [[Microprocessor|processor]]s based on [[GAMESS (US)]] sources. However, it has been mostly rewritten (60-70% of the code), especially in platform-specific parts ([[memory allocation]], disk [[input/output]], [[computer network|network]]), [[mathematic]] functions (e.g., [[Matrix (mathematics)|matrix]] operations), and [[quantum chemistry]] methods (such as [[Hartree–Fock method]], [[Møller–Plesset perturbation theory]], and [[density functional theory]]). Thus, it is significantly faster than the original GAMESS. The main maintainer of the program is Alex Granovsky. Since October 2008, the project is no longer associated with [[GAMESS (US)]] and the Firefly rename occurred. Until October 17, 2009, both names could be used, but thereafter, the package should be referred to as Firefly exclusively.<ref name="bare_url">[http://classic.chem.msu.su/gran/gamess/ Firefly Home Page]</ref>
==History==
On December 4, 2009, the support of any PC GAMESS versions earlier than the first PC GAMESS Firefly version 7.1.C was abandoned, and any and all licenses to use the code were revoked. Thus, users of the outdated PC GAMESS binaries (version 7.1.B and all earlier releases) were required to discontinue using the PC GAMESS and upgrade to Firefly.<ref name="bare_url" />
